Description

Learning how to build mosaics within PixInsight has been near the top of my "to do" list for several years. Now I have finally taken the plunge of attempting to learn the process.

This is a 9 panel mosaic built using 43GB of Nikon D810 DLSR data very generously shared by AstroBin member Wei-Hao Wang. It was captured using a Sigma 180mm f/2.8 APO lens over 7 imaging nights during 2016 and 2017.

A key lesson learned from this exercise is that trying to achieve seamless results with large mosaics involves considerable work! Two full weekends plus a couple of evenings later, I now have immense respect for the mosaic masters on AstroBin!

Thanks for looking, and CS to all!
